查询词典 datum level

First, experimental datum is analyzed and it is found that the shallow water ocean internal wave spectrum is different from that of the deep ocean GM spectrum. Then, the theory of weak turbulence is systematically summarized, and Lvov and Tabak's method of obtaining the deep ocean internal wave spectrum is introduced. They applied the theory of weak turbulence to internal waves of long wave length and found that GM spectrum maybe obtained theoretically.

作者采用绝对均值法和莱因达法分别对三组实测数据进行坏点数据的剔除处理，对处理结果的分析对比表明运用绝对均值法剔除动态测试数据中的坏点数据比莱因达法效果更好。

Compared with traditional invasion detection system has a lot of advantages to invade the detection system distributed: Distributed IDS is that a lot of measures the land to different data sources, adopts different measuring algorithms, measure together, cooperate and deal with, has improved the accuracy measured ; But distributed IDS can be used in the extensive network environment; Distributed IDS may use the special package to be punish and audit datum safely, help the system to be produced and invade the rule of measuring and produce and unusually measure models ; Distributed IDS analyses the behaviors of a lot of control points in coordination, may measure out and attack distributed in coordination ; The measuring of distributed IDS right a certain control point can be regarded as the early warning of other check points .

分布式入侵检测系统跟传统的入侵检测系统相比有很多优点：分布式IDS是多个检测域针对不同的数据来源，采用不同的检测算法，共同检测，协作处理，提高了检测的准确性；分布式IDS却可以用于大规模的网络环境；分布式IDS可以使用专门的组件处理安全审计数据，帮助系统生成入侵检测规则和生成异常检测模型；分布式IDS协同分析多个监控点的行为，就可能检测出分布式协同攻击；分布式IDS对某个监控点的检测可以作为对其他检测点的预警。

For example of the Shiyang River Basin along the Hexi Corrider,in Gansu province,made the imitial research of the major crop water production function and irrigation schedule optimal model,the results are following: 1Based on the related experimental datum gathered,drawing the relationship curve of several major crop yield and evapotranspiration,such as spring wheat,spring wheat-corn strip field,seed melon,sweet melon,cotton and flax and so on. The result shows these there:linearity and non-linear between crop yield and evapotranspiration.

本研究以甘肃省河西走廊石羊河流域为例，对其主要农作物的水分生产函数及灌溉制度优化模型作了初步研究，取得了以下成果： 1 根据收集的有关试验资料，绘制了春小麦、春小麦-玉米带田、籽瓜、白兰瓜、棉花和亚麻等几种主要农作物产量与耗水量的关系曲线，结果表明，产量与耗水量之间一般存在着线性与非线性的关系。

As mentioned Live/Google maps use a Mercator projection, but although their datum is based on WGS84, they use a sphere instead of an ellipsoid.

上文所说Live Map / Google Map 使用墨卡托投影，但虽然他们的大地基准应该是基于WGS84的，他们用球体模型替换了椭球体模型。

Because heart-sound is a highly nonstationary signal, this paper presents the application of adaptive filter method to the elimination of noise, and at the same time, employs the datum of heart-sound plot as the reference noise.
